INSTALLATION
Page 5
INLET & OUTLET

We strongly recommend the use of flexible hoses to
connect the appliance to the water distribution system; use
hoses with a large diameter in order to limit the pressure
loss.

If the appliance is not equipped with the factory bypass
(optional), we strongly recommend to install a 3-valve
bypass system (not included with this product!) to isolate the
appliance from the water distribution system in case of
repairs. It allows to turn off the water to the appliance, while
maintaining (untreated) water supply to the user.
WITH FACTORY BYPASS (optional)

1. Screw the factory bypass onto the in/out ports on the
control valve (
 &  ); make sure to install the gasket
seals. Tighten the nuts firmly by hand.
2. Screw the connection kit with nuts onto the factory
bypass (

Tighten the nuts firmly by hand.
3. Connect the mains water supply to the adaptor on the
inlet port of the factory bypass (

4. Connect the house/application to the adaptor on the
outlet port of the factory bypass (

5. Connect the house/application to the outlet of the 3-valve
bypass system.
DRAIN

We recommend the use of a stand pipe with P-trap.

To prevent backflow from the sewerage system into the
appliance, always install and use the included drain adaptor
with air gap and double hose barb, to connect the drain hose
to the sewerage system.

Lay-out the drain hose in such a way that pressure loss
is minimized; avoid kinks and unnecessary elevations.

Make sure that the sewerage system is suitable for the
rinse water flow rate of the appliance.

1. Install the drain adaptor to the sewerage system; it fits
over a 32 mm pipe or inside a 40 mm pipe adaptor. Ensure
a permanent and watertight connection.
2. Connect a 13 mm hose to the drain connection of the
control valve (
 ); secure it by means of a clamp.
3. Run the drain hose to the drain adaptor and connect it to
one of the hose barbs; secure it by means of a clamp. This
drain line operates under pressure, so it may be installed
higher than the appliance.
